Dear Madam or Sir, I would like to use your SAF1144C Single Angle Facet Gain Chip, but my setup requires a Ø9mm package, for instance as used in M9-915-0300. Could you provide the Ø9mm packaging also for the SAF1144C? Thank you, Barbara -- Laser & Electro-Optic Solutions via della Terra, 47 I-38068 Rovereto Italy email:

Hello Barbara, thank you for contacting Thorlabs. In most applications, both facets of the SAF1144C are used, and in my experience most 9mm diameter packages have only 1 window from which light could enter or exit the package. I will reach out to you directly about the geometry of your application.

Could you send a custom quote for SAF1144H with a 90% reflectivity coating instead of 10?

Response from Jeremy at Thorlabs: We will get in contact with you on the quote.

Response from Buki at Thorlabs: The standard SAF1144H with 10% AR coating has a cavity length of 2mm. For a 90% AR equivalent of SAF1144H, we would recommend a 1mm cavity length. We can provide a custom version with a 90% AR coating and we will contact you directly to discuss the details.

Hello, this is rather a question than a comment. I would like to ask if the SAF1144H gain chip is also available with the 90% normal facet reflectivity (as is offered with the 1450nm gain chip). I would like to use both chips in identical external cavity laser designs for compatibility. Thank you in advance for your information, with best regards, Ondrej Votava, Ph.D.
